DETAILED DESCRIPTION OF THE INVENTION

[0011] The data storage device of the present invention is placed in an insulated sealed housing, and the power interface of the data storage device is connected to the wireless power transmission unit. The wireless power transmission unit is a coupling coil arranged in the sealed housing and can be coupled to a coil outside the housing to power the data memory. The sealed enclosure is evacuated or filled with an inert gas to prevent oxidation of internal components.

Embodiment 1

[0012] Referring to FIG. 1, the data transmission interface of the data memory is connected to the wireless data transmission unit. A simplified example of the wireless data transmission unit is a capacitor plate, which can form a capacitor with another capacitor plate outside the sealed housing to achieve penetrating data transmission in a sealed enclosure. The wireless data transmission unit may also use relatively complex and mature existing technologies such as WiFi and Bluetooth.

[0013] The power supply part of this embodiment adopts the coupling coil method to realize wireless power transmission.

Embodiment 2

[0014] Referring to FIG. 2, the wireless data transmission unit of this embodiment adopts optical signal transmission technology, and a light medium window (such as transparent organic glass) is provided on the sealed housing as a transmission channel for optical signals. The power supply part adopts the method of coupling coil to realize wireless power transmission.

Embodiment 3

[0015] Referring to FIG. 3, this embodiment adopts one set of coils to achieve two functions of data communication and power transmission. The modem, which comprises the antenna outside the sealed housing and the antenna inside the sealed housing, realizes data transmission. The antenna itself can also be used as a carrier for power transmission, by using prior arts extracting electric energy from the antenna.

[0016] In FIGS. 1-3, Vdd and GND represent high level and ground level, which are used to represent electrical energy. Square waves represent signals.
